Yes, I am aware of a US product that uses a treated bentonite clay
substrate to selectively adsorb hydrocarbons.
Basically, the ballast water would be run through a filter containing this
material and it would act somewhat like carbon. The adsorbed material is
highly stable and pilot tests have shown it not to leach any organics. The
final material could then be landfilled with minimal impact on the
environment. Another option would be to use it as a fuel, since the final
material will have a high BTU value.
This looks like a good application. Do you have funds to do some pilot
testing?
